Hi Phiro,

I'm aware of the naming / layer selection feature, but it's quite different than a grouping (or combiner) system that "lock" a collection of objects into a single item ... and behave as a single object in the viewport when it comes to selection and manipulation.
If I build a restaurant scene, with 20 tables, I don't want to manually duplicate and rename table01, table02 so I can easily re-select them individually later using a scene browsing tree . I would rather combine the table elements into a group, and duplicate (instance ?) and transform that 'table' group.

Maybe it's out of the scope of MoI and scene assembly should be done in an other software. I'm fine with that too.
